MUCH better, I'd say 300% improvement
-The lighting is just, well lights, it doesn't cast shadows or such, it is also right at the focal of the sig, and thus distracts and sharpens unwanted areas of the face. Try moving it more to the right, and lowering the opacity for starters.
-The C4D's are a little too sharp, try blending them more, blending options would help too
-No big complaint on the background, besides it's a little blah
-The border looks nice in some places, but where it crosses the render and the text, it looks bad. I don't really have a good suggestion for this since it is a blending option. I'd say scrap it.
-Text needs a lot of work
-More C4D blending with the background and render
-Make the background more interesting
-Blend the edges of the render with the background
I'm not going to rate it as you have come very far, but still have a lot to learn.
Try looking up some photography tutorials, such as rules and general effects to learn some about photography, as well as photoshop. Rule of thirds, exposure and noise are good places to start.
I would like to see you make revisions to this, rather than make a new sig. Unlike your last, this has potential.
